Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 99 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. It is spread thinly across 28 manufacturers, the largest accounting for just 22.5% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2020 at $447 and has fallen 50.0% since, to $224 in 2025.
